An electronic device that performs methods of providing a notificationaccording to various exemplary embodiments may be, for example, theelectronic device 110 a illustrated in FIG. 2 that includes theprocessor 210, the notification providing unit 220, and thecommunication unit 230. However, embodiments of the present inventionare not limited to the electronic device 110 a of FIG. 2 and methods ofproviding a notification may be performed by electronic devices havingvarious structures according to exemplary embodiments. Exemplaryembodiments performed by the electronic device 110 a of FIG. 2 will bemainly described.

The processor 210 obtains information indicating whether the at leastone wearable device 120 is worn by a user (operation S702).

According to one exemplary embodiment, the information indicatingwhether the at least one wearable device 120 is worn includes sensingvalues of sensors included in the at least one wearable device 120.According to the current exemplary embodiment, the processor 210 maydetermine whether the at least one wearable device 120 is in the wearingstate or the non-wearing state, based on the information indicatingwhether the at least one wearable device 120 is worn.

According to another exemplary embodiment, the information indicatingwhether the at least one wearable device 120 is worn is informationregarding whether the at least one wearable device 120 is in the wearingstate or the non-wearing state. According to the current exemplaryembodiment, the at least one wearable device determines whether the atleast one wearable device 120 is in the wearing state or the non-wearingstate.

According to one exemplary embodiment, the processor 210 may obtain theinformation indicating whether the at least one wearable device 120 isworn by requesting the at least one wearable device 120 to provide thisinformation.

According to another exemplary embodiment, the at least one wearabledevice 120 may periodically transmit the information indicating whetherthe at least one wearable device 120 is worn to the electronic device110 a, and the electronic device 110 a may store this information in astorage unit thereof (not shown). The processor 210 may obtain theinformation stored in the storage unit to determine a device to whichthe notification regarding the notification event is to be provided.

Next, when it is determined that the at least one wearable device 120 isin the wearing state (operation S704), the processor 210 requests the atleast one wearable device 120 to provide the notification (operationS706). When it is determined that any one of the at least one wearabledevice 120 is not in the wearing state (operation S704), thenotification providing unit 230 of the electronic device 110 a providesthe notification (operation S708).

According to the current exemplary embodiment, a notification may beprovided to a wearable device that is in the wearing state, therebyincreasing a probability that a user will check the notification.

FIG. 8 is a flowchart of a method of determining a device that willprovide a notification when there are a plurality of wearable devices ina wearing state, according to an exemplary embodiment. The exemplaryembodiment of FIG. 8 is applicable to embodiments in which whether awearable device that is in a wearing state exists is determined.

When it is determined that there are wearable devices that are in thewearing state (operation S802—YES), the processor 210 determines whetherthe number of the wearable devices in the wearing state is more than one(operation S806). When it is determined that there are no wearabledevices that are in the wearing state (operation S802—NO), theelectronic device provides the notification (operation S804). When it isdetermined that there is one wearable device in the wearing state(operation S806—NO), the wearable device that is being worn is requestedto provide a notification (operation S808).

When it is determined that there are a plurality of wearable devices inthe wearing state (operation S806—YES), it is determined whether awearable device that is in use is present among the plurality ofwearable devices in the wearing state (operation S810). The processor210 may request the plurality of wearable devices that are being worn toprovide information indicating whether they are in use to determinewhether the plurality of wearable devices are in use.

In one exemplary embodiment, the wearable device 120 or the electronicdevice 110 may be determined to be in use if the wearable device 120 orthe electronic device 110 have received input from the user within apredetermined time, are reproducing content, the wearable device 120 orthe electronic device 110 are executing an application, the wearabledevice 120 or the electronic device 110 are being operated in somemanner by a user, or a sensor of either the wearable device 120 or theelectronic device 110 is detecting the use of the wearable device 120 orthe electronic device 110 by the user. The states of the wearable device120 and the electronic device 110 may be stored in the electronic device110, wearable device 120 or both. In addition, the state of both devicesmay be updated periodically or upon request of an application or a userby receiving information about use from the wearable device 120 or theelectronic device 110.

When a wearable device in use is present among the plurality of wearabledevices in the wearing state, the wearable device that is in the wearingstate and in use is requested to provide the notification (operationS812). When no wearable device in use is present among the plurality ofwearable devices in the wearing state, one of the plurality of wearabledevices in the wearing state is requested to provide the notification,based on set priorities (operation S814).

According to one exemplary embodiment, the set priorities may becriteria determined in consideration of a user's state, a remainingcharge capacity of a battery, etc. When a plurality of wearable devicesin the wearing state are present, additional criterion may be used todetermine a wearable device to which the notification is to be provided.

According to another exemplary embodiment, the set priorities may bepreset priorities.

FIG. 9 is a table illustrating preset priorities according to anexemplary embodiment.

The preset priorities are priorities determined beforehand by a designeror set by a user.

According to the current exemplary embodiment, the preset priorities areallocated to wearable devices that will provide a notification, based onthe type of the notification. For example, in the case of a soundnotification, priorities may be sequentially allocated to smart glasses,a smart watch, and a smart band. In the case of a vibrationnotification, priorities may be allocated to the smart watch, the smartband, and the smart glasses. In the case of a screen notification,priorities may be sequentially allocated to the smart glasses and thesmart watch.

In addition, priorities may be allocated to wearable devices regardlessof the type of the notification.

FIG. 10 is a diagram illustrating a method of providing a notificationwhen there are a plurality of wearable devices in a wearing stateaccording to an exemplary embodiment.

As in the exemplary embodiment described above with reference to FIG. 8,when a plurality of wearable devices are in the wearing state, only oneof the plurality of wearable devices is provided with a notification inconsideration of the usage states of the wearable devices and setpriorities, thereby preventing a notification from being excessivelyprovided to a user. For example, according to the current embodiment,when two wearable devices, e.g., smart glasses 120-1 and a smart watch120-2, are in the wearable device as illustrated in FIG. 10, anotification is provided to only the smart glasses 120-1, consideringwhether the smart glasses 120-1 and the smart watch 120-2 are in use,the set priorities, etc. If the notification is provided to both thesmart glasses 120-1 and the smart watch 120-2 in the case of FIG. 10, auser may be startled or provided with the notification more thannecessary. Accordingly, according to the current exemplary embodiment,it is possible to appropriately provide a notification while minimizinginterruptions that may be caused to the user.

FIG. 11 is a flowchart of a method of providing a notification accordingto an exemplary embodiment.

FIG. 29 is a flowchart of a method of determining a device to which anotification is to be provided according to another exemplaryembodiment.

According to the current exemplary embodiment, the processor 210 of theelectronic device 110 a or 110 b considers whether a recognizable deviceis present to determine a device to which a notification is to beprovided.

When it is determined that recognizable device is present (operationS2902), the processor 210 requests the recognizable device to provide anotification (operation S2904). When it is determined that arecognizable device is not present (operation S2902), the processor 210determines a device that will provide the notification, based on setpriorities (operation S2906) and requests this device to provide thenotification (operation S2908).

For example, in operations S814, S1112, S1414, S1504, S1510, and S1610,the exemplary embodiment of FIG. 29 may be one of the set prioritieswhen a device to which the notification is to be provided is determinedbased on the set priorities.

FIG. 30 is a table illustrating criteria for determining whether adevice is a recognizable device and a non-recognizable device accordingto an exemplary embodiment.

According to one exemplary embodiment, the processor 210 determineswhether a recognizable device is present. That is, the processor 210only determines whether a recognizable device is present, and determinesa current state as a non-recognizable state when there is norecognizable device. A device that is held with a user's hand, a devicethat is held by a car holder but a navigation function is not runtherein, a device in which music is played back, a device via which aconversation is being conducted, a device in which user's eye contact isdetected, etc. may be determined a recognizable device. According to thecurrent exemplary embodiment, the processor 210 does not determinewhether a device is in a non-recognizable state.

When pressure having a reference level or more is detected by a pressuresensor included in a housing of a device and a motion is sensed, thedevice may be determined as a device that is held with a user's hand. Asanother example, a device may be determined as a device that is heldwith a user's hand when a fingerprint is recognized or a temperature issensed.

Whether the electronic device 110 or the at least one wearable device120 is combined with a car holder may be determined using a sensorincluded in an interface between the car holder and the electronicdevice 110 or the at least one wearable device 120. For example, whetherthe electronic device 100 is combined with the car holder may bedetermined using a magnetic sensor, a hall sensor, a conductive sensor,a piezoelectric sensor, or the like that is included in a housing of theelectronic device 110 that contacts or that is combined with the carholder. As another example, whether the electronic device 110 or the atleast one wearable device 120 is combined with the car holder may bedetermined by detecting whether an electrode of the car holder contactsan electrode of the electronic device 110 or an electrode of the atleast one wearable device 120 or by exchanging a signal between theseelectrodes.

That music is being played back may be perceived through a function thatis being performed in a device.

That a conversion is being conducted may be perceived by receivingexternal voice using a microphone and perceiving a predetermined patternof the external voice. For example, that a conversation is beingconducted may be perceived by sensing repetitive voice of a specificperson.

User's eye contact may be detected by capturing an image using a cameradisposed near a display unit of the electronic device 110 or the atleast one wearable device 120 and detecting the eyes of a user from theimage.

FIG. 31 is a diagram illustrating a method of detecting a line of sightaccording to an exemplary embodiment.

According to the current exemplary embodiment, an electronic device 110or a wearable device 120 may include a display unit 3120 and a camera310 capable of photographing a subject that the display unit 3120 faces.According to the current exemplary embodiment, the processor 210 of theelectronic device 110 or the processor 610 of the at least one wearabledevice 120 may detect a line of a user's sight of by photographing asubject that the display unit 3120 faces by using the camera 3110. Forexample, whether the line of the user's sight is toward the electronicdevice 110 or the wearable device 120 may be determined by detecting theeyes of the user from an image the camera 3110.

According to the current exemplary embodiment, the electronic device 110may perceive that the line of the user's sight is toward the electronicdevice 110 itself rather than the at least one wearable device 120.

According to another exemplary embodiment, the processor 210 maydetermine whether a non-recognizable device is present and determine acurrent state as a recognizable state when a non-recognizable device isnot detected. In this case, the processor 210 does not determine whethera device is recognizable. For example, the processor 210 may determinethat a device is in a non-recognizable state when a user is driving acar, is on the move, or is in a movie theater, when the device is in ado-not-disturb mode or in an airplane mode, when a phone call isconducted using the device, when the device is put in a bag or pocket,etc.

That the user is driving a car may be detected using the motion of asmart watch, a smart ring, or a smart bracelet. For example, it may bedetermined the user is driving a car when a motion of steering a handleis detected by a smart watch, a smart ring, or a smart bracelet. When anavigation function is run the electronic device 110 or the at least onewearable device 120, the processor 210 may also perceive that the useris driving a car. When an image viewed through front glass of anautomobile, an image of a dashboard, an image of a side mirror, etc. isdetected by a camera of smart glasses, it may also be determined that auser is driving a car.

When an irregular motion of the electronic device 110 or the wearabledevice 120 is detected together with a change in the location thereof,it may be determined that a user is on the move.

When the intensity of illumination is a reference level or less and aposition detection module detects that a user is in a movie theater, itmay be determined that the user in the movie theater. When an image of amovie theater is captured by a camera of smart glasses, it may also bedetermined that a user in a movie theater.

The do-not-disturb mode, the airplane mode, etc. may be perceived bydetermining a mode set in a device.

That a user is making a phone call may be perceived by detecting afunction that is being performed in a device.

When the intensity of illumination sensed by an illumination sensor isequal to a reference level or less and a proximity sensor senses that anobject is adjacent to a device, it may be determined that the device isput in a bag or a pocket.

According to another exemplary embodiment, the processor 210 may detectcases in which a device is in a recognizable state or in anon-recognizable state and may not consider whether the device can berecognized when the device is neither in the recognizable state nor thenon-recognizable state.

According to the current exemplaryembodiment, the processor 210 determines a device that will provide thenotification and a form of the notification based on the states of theelectronic device 110 and the at least one wearable device 120.

Since the form of the notification is also considered based on thestates of the electronic device 110 and the at least one wearable device120, a probability that a user will immediately check the notificationmay be increase and interruptions that may be caused to the user may beminimized.

When the device that will provide the notification and the form of thenotification are determined, the device that will provide thenotification is requested to provide the notification (operation S3908).

FIG. 40 is a flowchart of a method of determining a form of anotification according to an exemplary embodiment.

According to the current exemplary embodiment, when a form of anotification is set for the electronic device 110 or the at least onewearable device 120, the notification is provided in the set form.According to one exemplary embodiment, the form of the notification mayvary according to the type of an event.

When a form of the notification is set for a device determined toprovide the notification (operation S4002), the processor 210 requeststhe device to provide the notification in the set form (operationS4004). When a form of the notification is not set for a devicedetermined to provide the notification (operation S4002), the processor210 determines a form of the notification based on a predeterminedcriterion (operation S4006) and requests the device determined toprovide the notification to provide the notification in the form(operation S4008).

For example, the predetermined criterion for determining the form of thenotification includes determining the form of the notification accordingto the type of the notification event, providing the notification in aform that is set as a default, etc.

FIG. 41 is a flowchart of a method of setting a form of a notificationaccording to an exemplary embodiment.

According to the current exemplary embodiment, a form of a notificationmay be set for all of the wearable devices 120-1 and 120-2 connected tothe electronic device 110 to establish communication with the electronicdevice 110 (operation S4102). For example, the electronic device 110 mayset a sound notification as the form of the notification of the smartglasses 120-1 and turn off the notification of the smart watch 120-2according to user input as illustrated in FIG. 41.

When the electronic device 110 sets a form of the notification of atleast one wearable device among the wearable devices 120-1 and 120-2(operation S4102), the electronic device 110 informs the at least onewearable device of the set form of the notification (operation S4104).For example, when the electronic device 110 does not change the form ofthe notification of the smart glasses 120-1 and changes the form of thenotification of the smart watch 120-2, a control signal for setting theform of the notification may be transmitted to the smart watch 120-2 forwhich the form of the notification is changed. The at least one wearabledevice 120-1 or 120-2 that receives the control signal from theelectronic device 110 may set the form of the notification thereofaccording to the control signal (operations S4106 and S4108).

FIG. 42 is a flowchart of a method of setting a form of a notificationaccording to an exemplary embodiment.

Forexample, when a user sets a form of the notification of the smart watch120 as a vibration notification (operation S4202), the smart watch 120informs the electronic device 110 of this fact (operation S4204). Whenthe electronic device 110 receives the information that the form of thenotification of the smart watch 120 is set as the vibration notificationfrom the smart watch 120, the electronic device 110 stores and managesthe information (operation S4206).

FIG. 43 is a flowchart of a method of determining a form of anotification according to an exemplary embodiment.

According to the current exemplary embodiment, when a device that willprovide a notification is determined, the processor 210 determineswhether the device is in a situation that is not appropriate forproviding a sound notification (operation S4302). Here, the situationthat is not appropriate for providing a sound notification means asituation in which a user is not likely to recognize the soundnotification due to surrounding noise or that is interrupted by thesound notification. The situation that is interrupted by the soundnotification may include, for example, when a user is attending alecture or is in a movie theater, etc.

According to one exemplary embodiment, information for determiningwhether the device is in a situation that is not appropriate forproviding the sound notification may be obtained by a device capable ofobtaining this information among the electronic device 110 and the atleast one wearable device 120. For example, in order to obtain theinformation whether the user is attending a lecture or is in a movietheater, smart glasses may capture an image by using a camera, theprocessor 210 of the electronic device 110 or the smart glasses mayrecognize a current situation based on the image captured by the smartglasses, and the processor 210 may determine that both the electronicdevice 110 and the at least one wearable device 120 are in the situationthat is not appropriate for providing the sound notification when theuser is attending a lecture.

When the device is not in the situation that is not appropriate forproviding the sound notification (operation S4302), the processor 210determines a form of the notification, including the sound notification(operation S4304). When the device is in the situation that is notappropriate for providing the sound notification (operation S4302), theprocessor 210 determines a form of the notification excluding the soundnotification (operation S4306).

FIG. 44 is a table illustrating a list of cases in which a soundnotification is not appropriate according to an exemplary embodiment.

According to the current exemplary embodiment, the processor 210 maydetermine a case in which a noise level is equal to or greater than areference level, a case in which a user is attending a lecture, a casein which a user is in a movie theater, etc., as situations in which asound notification is not appropriate. The processor 210 may receivenoise via a microphone included in the electronic device 110 or thewearable device 120 and determine whether the level of the noise isequal to or greater than a reference level. Whether a user is attendinga lecture or is in a move theater may be determined based on an imagecaptured by a camera included in smart glasses.

FIG. 45 is a table illustrating examples of a predetermined device thatwill provide a notification and a predetermined form of the notificationaccording to an exemplary embodiment.

According to one exemplary embodiment, the processor 210 may determine adevice that will provide a notification and a form of the notificationbased on predetermined criteria. FIG. 45 illustrates examples ofpredetermined criteria for a device that will provide a notification ofa notification event except for a phone call and a form of thenotification when the smart watch 120 and the electronic device 110 areused together.

When pressure having a reference level or more is detected by a pressuresensor included in a housing of the electronic device 110 or thewearable device 120 and the electronic device 110 or the wearable device120 is neither on a table nor in a pocket or a bag, it may be determinedthat the electronic device 110 or the wearable device 120 is held with auser's hand.

When acceleration perpendicular to a direction of gravity is detectedand a motion is not detected, the electronic device 110 or the wearabledevice 120 may be determined that it is on a table.

FIG. 56 is a flowchart of a method of providing a notification accordingto an exemplary embodiment. FIG. 56 illustrates a detailed example ofthe embodiment of FIG. 55.

When a notification event that an increase in a heart rate should beinformed occurs while the wearable device 120 monitors the heart rate(operation S5602), the wearable device 120 in which the notificationevent occurs determines a device that will provide a notification, basedon the states of the electronic device 110 and the at least one wearabledevice 120 (operation S5604). When it is determined that the electronicdevice 110 will provide a notification (operation S5604), the at leastone wearable device 120 transmits a notification request to theelectronic device 110 (operation S5606).

When the electronic device 110 receives the notification request, theelectronic device 110 provides a notification regarding the increase inthe heart rate, based on the contents of the notification request(operation S5608). For example, when the notification request indicatesturning on a screen, outputting sound, and displaying a messageindicating the increase in the heart rate as a form of the notification,sound is output and the message is displayed as illustrated in FIG. 56.

FIG. 57A is a flowchart of a method of providing a notificationaccording to an exemplary embodiment.

According to the current exemplary embodiment, the electronic device 110and at least one wearable device, e.g., the first and second wearabledevices 120-1 and 120-2, share information regarding the states thereofregardless of whether a notification event occurs, and a device in whicha notification event occurs determines a device that will provide anotification. FIG. 57A illustrates a case in which the notificationevent occurs in the first wearable device 120-1.

The electronic device 110, the first wearable device 120-1, and thesecond wearable device 120-2 detect the states thereof (operationsS5702, S5706, and S5710), and broadcast information regarding the statesthereof to one another (operations S5704, S5708, and S5712).

According to one exemplary embodiment, the information regarding thestates of the devices may be periodically detected and broadcast.According to one exemplary embodiment, the information regarding thestates of the devices may also be sequentially detected and broadcast ina predetermined order. For example, the information regarding the statesof the devices may be sequentially detected and transmitted in the orderof the first wearable device 120-1, the electronic device 110, and thesecond wearable device 120-2.

According to another exemplary embodiment, the detecting andbroadcasting of the information regarding the states thereof may beperformed after a change in this information is detected. For example,the first wearable device 120-1 may broadcast the information regardingthe states of the devices, which indicates a changed state of the firstwearable device 120-1, only when the state of the first wearable device120-1 changes. In another example, the second wearable device 120-2 maybroadcast the information regarding the states of the devices, whichindicates a changed state of the second wearable device 120-2, only whenthe state of the second wearable device 120-2 changes. In yet anotherexample, the electronic device 110 may broadcast the informationregarding the states of the devices, which indicates a changed state ofthe electronic device 110, only when the state of the electronic device110 changes.

The information regarding the states of the devices may include, forexample, information indicating whether the first wearable device 120-1or the second wearable device 120-2 is worn by a user, and informationindicating whether the first wearable device 120-1, the electronicdevice 110, or the second wearable device 120-2 is being used by theuser.

For example, when a change in an attached/detached state of the firstwearable device 120-1 is detected, information regarding thewearing/not-wearing state (e.g., state information indicating whetherthe device is attached to a user) of the first wearable device 120-1 maybe broadcast to the electronic device 110 and the second wearable device120-2. As another example, when a degree of a change in a heart ratedetected by the second wearable device 120-2 is a reference level ormore, information regarding the heart rate detected by the secondwearable device 120-2 may be broadcast to the electronic device 110 andthe first wearable device 120-1.

According to an exemplary embodiment, when the wearable device 120 is asmart watch, the smart watch may determine whether there is a change ina wearing state of the smart watch, by sensing one or more of aconnection state of a clasp of the smart watch by using a sensor (forexample, a conductive sensor, a hall sensor, a magnetic sensor, etc.)included in the clasp of the smart watch, by sensing a motion of thesmart watch by using a motion sensor in the smart watch, or by detectinga bio-signal of a user by using a bio-sensor in the smart watch.

When the wearing state of the smart glasses changes, the smartglasses may broadcast information indicating the change in the wearingstate.

According to an exemplary embodiment, when the wearable device 120 is anearphone, the earphone may determine whether there is a change in awearing state of the earphone, based on a sensing value that is sensedby using one or more of a heartbeat sensor disposed in an outercircumferential portion of the earphone, and a temperature sensordisposed in a soundboard. When the wearing state of the earphonechanges, the earphone may broadcast information indicating the change inthe wearing state.

According to an exemplary embodiment, when the wearable device 120 issmart shoes, the smart shoes may determine whether there is a change ina wearing state of the smart shoes, based on a sensing value that issensed by using one or more of a heartbeat sensor, a temperature sensor,a perspiration sensor, and a piezoelectric sensor that are disposed in aheel insert of the smart shoes, and an accelerometer sensor, a motionsensor, and a position sensitive detector module that are disposed in abody, a sole, and the heel insert of the smart shoes. When the wearingstate of the smart shoes changes, the smart shoes may broadcastinformation indicating the change in the wearing state.

Although the above exemplary embodiment describes a case in which thewearable device 120 broadcasts information indicating a change in thewearing state of the wearable device 120 when there is the change in thewearing state, the exemplary embodiments are not limited thereto. Thewearable device 120 may broadcast information indicating a usage stateof the wearable device 120 when there is a change in the usage state ofthe wearable device 120. For example, the wearable device 120 maybroadcast information indicating whether the wearable device 120 is inuse and information regarding an operation executed in the wearabledevice 120.

When a notification event is detected in one of the electronic device110 and the first and second wearable devices 120-1 and 120-2 (operationS5714), the device in which the notification event occurs determines adevice that will provide a notification (operation S5716). If thenotification event occurs in the first wearable device 120-1 (operationS5714), the first wearable device 120-1 determines a device that willprovide the notification (operation S5716).

If it is determined that a device except for the device in which thenotification event occurs determines a device that will provide thenotification, the device in which the notification event occurstransmits a notification request to the device that will provide thenotification (operations S5718 and S5720). When the electronic device110 or the second wearable device 120-2 receives the notificationrequest, the electronic device 110 or the second wearable device 120-2provides the notification (operations S5722 and S5726). If it isdetermined that the first wearable device 120-1 will provide thenotification, the first wearable device 120-1 provides the notification(operation S5724).

FIG. 57B is a flowchart of a method of providing a notificationaccording to an exemplary embodiment.

According to the current exemplary embodiment, when a notification eventis detected, the electronic device 110 and the at least one wearabledevice 120 detect and share information regarding the states thereof,and a device in which the notification event occurs determines a devicethat will provide a notification. FIG. 57B illustrates a case in whichthe notification event occurs in the first wearable device 120-1.

When the notification event is detected by one of the electronic device110 and the first and second wearable devices 120-1 and 120-2 (operationS5802), the device that detects the notification event requests theother devices to provide information regarding the states thereof(operation S5804). If the notification events occurs in the firstwearable device 120-1 (operation S5802), the first wearable device 120-1requests the electronic device 110 and the second wearable device 120-2to provide the information regarding the states thereof (operationsS5804 and S5806).

A device that receives the request to provide the information regardingthe state thereof detects the state thereof (operations S5808 andS5812), and transmits information regarding the states thereof to thedevice in which the notification event occurs (operations S5812 andS5814). The device in which the notification event occurs detects thestate thereof (operation S5810).

When the first wearable device 120-1 in which the notification event isdetected obtains the information regarding the states of the electronicdevice 110 and the second wearable device 120-2, the first wearabledevice 120-1 determines a device that will provide a notification, basedon the states of the electronic device 110, the first wearable device120-1, and the second wearable device 120-2 (operation S5816).

When it is determined that at least one device (except for the device inwhich the notification event occurs) will provide the notification, thedevice in which the notification event occurs transmits a notificationrequest to the at least one device that will provide the notification(operations S5818, S5820 and S5822). When the electronic device 110 orthe second wearable device 120-2 receives the notification request, theelectronic device 110 or the second wearable device 120-2 provides thenotification (operations S5824 and S5828). When it is determined thatthe first wearable device 120-1 will provide the notification, the firstwearable device 120-1 provides the notification (operation S5826).

FIG. 58 is a view illustrating an example of a smart watch 580 or smartglasses 582 broadcasting information indicating a change in a wearingstate thereof as the wearing state of the smart watch 580 or the smartglasses 582 changes.

Referring to FIG. 58, when a user removes the smart watch 580 fromhis/her wrist, the smart watch 580 may determine that the smart watch580 has been removed from the wrist of the user. The smart watch 580 maydetermine whether a clasp of the smart watch 580 is unclasped by using asensor disposed in the clasp of the smart watch 580, and may determinewhether to sense a bio-signal of the user via a bio-sensor disposed inthe smart watch 580. For example, if the clasp is unclasped and thesmart watch 580 activates the bio-sensor to sense the bio-signal of theuser, when the bio-signal of the user is not sensed, the smart watch 580may determine that the smart watch 580 is not attached to the wrist ofthe user. When it is determined that the smart watch 580 is not attachedto the wrist of the user, the smart watch 580 may broadcast informationindicating that the smart watch 580 is not attached to the wrist of theuser.

When the user takes off the smart glasses 582, the smart glasses 582 maydetermine that the smart glasses 582 are not on the face of the user.For example, when the smart glasses 582 sense that the user is holdingthe temples of the smart glasses 582, the smart glasses 582 may activatea heartbeat sensor disposed in the temples of the smart glasses 582 tosense the heartbeat of the user. When the heartbeat of the user is notsensed, the smart glasses 582 may determine that the smart glasses 582are not on the face of the user. When it is determined that the smartglasses 582 are not on the face of the user, the smart glasses 582 maybroadcast information indicating that the smart glasses 582 are not onthe face of the user.

FIG. 59 is a flowchart of a method of setting a form of a notificationaccording to an exemplary embodiment.

According to the current exemplary embodiment, an electronic device 110may set a form of notification of all of wearable devices 120-1 and120-2 connected to the electronic device 110 such that communication maybe established therebetween. After the form of the notification is set,the electronic device 110 may transmit information regarding the form ofthe notification to all of the wearable devices 120-1 and 120-2.

According to the current exemplary embodiment, the electronic device 110may set a form of notification of each of the wearable devices 120-1 and120-2 connected to the electronic device 110 such that communication maybe established therebetween (operation S5902). For example, theelectronic device 110 may set a form of the notification of the smartglasses 120-1 as a sound notification and turn off the notification ofthe smart watch 120-2 according to user input as illustrated in FIG. 59.

When the electronic device 110 sets the form of the notification of atleast one among the wearable devices 120-1 and 120-2 (operation S5902),the electronic device 110 transmits information regarding the form ofthe notification to all of the wearable devices 120-1 and 120-2(operation S5904). For example, when the electronic device 110 does notchange the form of the notification of the smart glasses 120-1 andchanges the form of the notification of the smart watch 120-2, theelectronic device 110 transmits information regarding the form of thenotification of the smart watch 120-2 to the smart watch 120-1 and thesmart watch 120-2. According to one exemplary embodiment, the electronicdevice 110 may transmit a control signal for setting the form of thenotification to a device for which the form of the notification ischanged.

Next, a device that receives the information regarding the form of thenotification stores this information (operations S5906 and S5908). Whenthe information regarding the form of the notification is informationregarding the form of the notification of the device, the form of thenotification of the device is set based on the information regarding theform of the notification. For example, when the electronic device 110changes and sets the form of the notification of the smart watch 120-2,information regarding the form of the notification of the smart watch120-2 is transmitted to the smart glasses 120-1 and the smart watch120-2. The smart watch 120-2 may also change the form of thenotification thereof, based on the information regarding the form of thenotification or according to the control signal for setting the form ofthe notification which is transmitted from the electronic device 110(operation S5908).

FIG. 60 is a flowchart of a method of setting a form of a notificationaccording to an exemplary embodiment.

According to the current exemplary embodiment, each wearable device mayset a form of a notification thereof and broadcast information regardingthe set form of the notification to the electronic device 110 and otherwearable devices.

For example, when the second wearable device 120-2 sets a form of thenotification thereof (operation S6002), the second wearable device 120-2broadcasts information regarding the set form of the notification to theelectronic device 110 and the other wearable device 120-1 (operationS6004). For example, when a user sets a form of the notification of thesmart watch 120-2 as a vibration notification (operation S6002), thesmart watch 120-2 transmits information indicating that the form of thenotification thereof is set as the vibration notification to the smartglasses 120-1 and the electronic device 110 (operation S6004). When thesmart glasses 120-1 receive from the smart watch 120-2 the informationindicating that the form of the notification of the smart watch 120-2 isset as the vibration notification, the smart glasses 120-1 store andmanage this information (operation S6006). The electronic device 110receives from the smart watch 120-2 the information indicating that theform of the notification of the smart watch 120-2 is set as thevibration notification, the electronic device 110 stores and managesthis information (operation S6008).
